Accepted answer

Your react code is not showing up because index.html is not including it. Is public/bundle.js your transpiled react code? If so, add the following line to index.html, right after <div id="root"></div>:

<script src="/public/bundle.js"></script>

If not, then change the path pointed by src to the correct one.

You can see your css styles just fine because you are already including those in index.html.

UPDATE: a couple of points based on your webpack config:

  • Change the port in which you are running webpack-dev-server to 3000. You will also have to change BrowserSyncPlugin's proxy to http://localhost:3000/. You can then go to localhost:3312 in your browser and requests will be proxied to the webpack-dev-server running on port 3000.

  • Correct me if I'm wrong, but you have not posted your index.html in its entirety. I'm guessing you already have a line that looks like <script src="/bundle.js"></script> somewhere in that .html file -- based on your latest comment, it seems it is being added by HtmlWebPackPlugin. webpack-dev-server is serving bundle.js through /, the publicPath you've specified in webpack's output option. This works just fine as long as you access your site through localhost:3312 or localhost:3000. However, your express.js server running on port 5000 has no idea webpack-dev-server is serving bundle.js at /; as a result of that, you end up seeing none of your react code when you go to localhost:5000. As for the styles, you are already serving them correctly through /public/assets/css, which the express.js server understands because you've specified that in this line: app.use("/public", express.static(__dirname + "/../public")). The solution is to change the line <script src="/bundle.js"></script> in your .html file to:

    <script src="http://localhost:3312/bundle.js"></script>

    Also, in webpack's output option, change the publicPath to http://localhost:3312/. Now, as long as you have webpack-dev-server running (with BrowserSyncPlugin), you can access your site at localhost:5000 and your bundle.js file should be served just fine.

Try the following:

Webpack Config

module.exports = {
    devServer: {
        contentBase: path.join(__dirname, "/public"),
        historyApiFallback: true,
        port: 3000,
        proxy: {
            "/api": "http://localhost:5000"
    entry: ["babel-polyfill", __dirname + "/src/index.js"],
    output: {
        path: path.join(__dirname, "/public"),
        filename: "bundle.js",
        publicPath: "http://localhost:3312/"
    module: {
        rules: [
                test: /\.jsx?$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader",
                    query: {
                        presets: ["react", "env", "stage-0"]
                test: /\.css$/,
                use: [
                    { loader: "style-loader" },
                    { loader: "css-loader" },
                    { loader: "sass-loader" }
    plugins: [
        new BrowserSyncPlugin({
            host: "localhost",
            port: 3312,
            files: [
            proxy: "http://localhost:3000/"

Oh sorry, it looks like the problem is in index.js. Change {Routes} to <Routes />

import React, { Component } from "react";
import ReactDOM from "react-dom";

import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(<div><Routes/></div>, document.getElementById("root"));

You have another problem in routes.js. Export a component like

import React from "react";

import { BrowserRouter as Router, Route, Switch } from "react-router-dom";

import HomePage from "./components/homepage";
import AboutPage from "./components/aboutpage";
import Contactpage from "./components/contactpage";

// make this a component
export default ()=>(
        <Route exact path="/" component={Landingpage} />
        <Route exact path="/about" component={AboutPage} />
        <Route exact path="/contact" component={Contactpage} />
